7.6.4 SMD INDUCTOR IDENTIFICATION
SMD inductors (P.N. 542-9000-xxx) use three
colored dots to indicate the value. The two dots on the
left side indicate the first and second digits of the
value in nanohenries, and the single dot on the right
side indicates the multiplier (see Table 7-2). For
example, brown, black, and red dots indicate a value
of 10 nH x 100 which is 1000 nH (1.0
µH). The last
three digits of the part number are also the value and
multiplier.
7.6.5 TRANSISTOR/DIODE IDENTIFICATION
Surface mounted transistors and diodes are identi-
fied by a special number. Refer to page 10-1 for more
information.
